I figured I'd resurrect this thread rather than start a new one, to cast my vote with those who swallow. In ther 1960s when I was in college I didn't have any objection to dating "bad girls" from local high schools, and in the 1960s they divided into two groups: Girls who were on the pill and swallowers. I am still fond of the first sweet little blonde who asked, "When you're ready to cum, can I take it in my mouth?" I didn't correct her grammar.
I guess I was lucky, because I didn't run into a spitter until the mid-1990s. And from my personal experience, I can tell you that there aren't any spitters over 55.
